CONTROLLING UNIT FOR OIL BUBNERS.

Application filed September 17, 1926. Serial No. 136,140.

This invention relates to a controlling unit for motor driven oil burners more particularly to a combined valvular, overflow collecting and terminal block unit for use in connection with oil burner installations, and "has for its object to provide, in a manner as hereinafter set forth, a unit of the character referred to, for simplifying oil burner installations, and further so constructed and arranged that the overflow collector, electrically operated controlling valve, manually operated regulating valve and electrical connections are completed in one unit withoutdanger of wrong electrical feed or job connections whereby, when the unit is employed the installation of an oil burner is eXpedi tiously had.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a controlling unit for oil burners, which is simple in its construction and arrangement, strong, durable, compact, thoroughly efficient in its use, quickly installed with respect to a burner, that is to say with respect to the electrical connections, oil and overflow lines, including an enclosing casing having means to permit of convenient access to the elements arranged therein, and comparative- 1y inexpensive to manufacture.

lVith the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically de' scribed, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

Figure 1 is a front elevation of a controlling unit in accordance with this invention.

Figure 2 is an elevation looking towards one side thereof.

Figure 3 is a vertical sectional view of the controlling unit.

Figure 4 is a top plan view thereof.

Referring to the drawings in detail a con trolling unit, in accordance with this invention, comprising a casing or housing includ ing a rear wall 1, a front wall 2, and an inner and an outer side wall 3-, 4 respectively.

The casing) or housing which is referred to generally y the reference character 5 in= eludes an open top and open bottom body portion which is provided by the walls 1, 2, 3 and 4. The wallsof the body portion at their lower ends are formed with right angu larly disposed supporting flanges 6 and any suitable means can be associatedwith the flanges 6 for fixedly securing the body portion in an upright position. The open top of the body portion of the casing 5 is indicated at 7 and the open bottom thereof at 8. The open top 7 of the body portion is closed by a removable flanged lid or cover 9. The front wall 2 of the body portion is constructed with a lower hinged section 10 provided at its lower end with a knob 11 to facilitate the opening movement thereof. The hinge for the section 10 is indicated at 12 and said section is set up with inturned flanges 13 to overlapthe side wall of the housing. The section 10 provides'a door or closure for the casing 5 whereby access can be had to the chamber 14 which is rovided in the casing 5 by a partition member 15 arranged below the top of the body portion. That part of the body portion above the partition 15 pro vides a chamber 16 which is normally closed by the lid 9 and the latter when removed from the body portion permits of access be ing had to the chamber 16. The chamber 14 is of greater height than the chamber 16.

The side wall 4 in proximity to the par tition 15 is formed with an opening 17 having the wall thereof extending upon an arc. The side wall 4 above the partition 15 is formed with an opening 18 of materially less size than the opening 17. The side wall 3 above the partition 15 is formed with an opening 19 and below the partition 15 with a series of spaced offset openings 20, 21 and 22. The purpose of the openings formed in the side walls 3 and 4 will be presently referred to.

Arranged within the chamber l l,'at the upper portion thereof, and extending through and bearing a ainst theedge of the opening 17 is the globu ar casing of a manually adjusted regulating valve 23. The means for manually adjusting the regulating valve 23 is arranged exteriorly of the casing 5 and indicated 31324:. The regulating valve 23, at one side is provided with an inlet nipple or connection indicated at 25 and the top of the regulating valve 23 is provided with an outlet 26 having a discharge nipple 27 connected therewith. The regulating valve 23 is secured in any suitable manner within the chamber 14. Extending through the opening 21 and connected to the inlet nipple or connection 25 is a pipe connection 28 which leads from the oil tank not shown. Clamping nuts 29 engage with the pipe connection 28 and abut against the inner and outer faces of the wall 3. The pipe connection 28 in connection with that part of the casing oi the valve 23 which is mounted in the opening 17 also act as supporting means for the said valve 23.

Extending through the opening 22 is a pipe connection 30 which leads from the overflow pipe for the burner, said pipe and burner are not shown, and threadably engaging with the pipe connection 30 is a pair of clamping nuts 31 which secure the pipe connection 7 to the wall 3 and said nuts 31 engage ;the outer and inner faces of said wall 3. The inner end of the pipe connection 30 is formed with a depending coupling 32, having a discharge nipple 33 depending therefrom and which opens into a collector 34 which is suitably secured or suspended within the chamber 14.

Extending through the partition 15, as well as being suitably secured therewith is a controlling valve of the electrical solenoid posts.

type and which is indicated at The major portion of the valve 35 is arranged within the chamber 16 and has one side at its lower end connected to and communicating with the discharge nipple 2'7 and its other side at its lower end connected to and communicating with a pipe branch 36 which is attached to and opens into the feed line leading-to the burner. The feed line and the burner is not shown. The nipple 27 and pipe 36 form a connection between the valve 23 and the feed line and is intersected by the valve 35. Clamping nuts 37 threadably engage with the pipe branch 36 for securing it to the wall 3 and said nuts abut against the inner and outer faces of said wall.

Mount-ed on, as well as being suitably connected with the partition 15, is a terminal block 38, provided with pairs of binding One pair is indicated at 39, the other pair at 40 and the otherpair at 11, see dotted line showing in Figure 1. The main electrical leads are indicated at 12 and are connected to the binding posts 39. The circuit con- Y nections for the solenoidvalve 35 are indi driven type, are indicated at 14: and are con-- nected to the binding posts 41. The main leads 42 extend through the opening 18 and the circuit connections 44 for the motor 6X-.

tend through the opening 19.

The pipe connection 28 is arranged to one side of the pipe branch 36 and the pipe connection 30 isarranged in substantial alinement with respect to the nipple E27 and pipe connection 28. See dotted line showing in Figure 2.

It is thought the many advantages of a controlling unit, in accordance with this invention, can be readily understood, particularly in view of the fact that it materially simplifies oil burner installations, and although the preferred. embodiment of the invention is as illustrated. and described, yet it is to be understood that changes in the details of construction can be had which will fall within the scope of the invention as cl aimed.
